Help me diagnose my car :(

[michael1284]

I'll give ya cliffs:

-Get in car. Feels like power steering is going out, when I turn it, it turns easy, then hard (like the PS going out).
-Open engine bay, notice that the belt slows way down almost to a halt when the wheel is turned and I hear the annoying screeching noise. (When wheel is turned almost all the way) Also the FAN slows down too since it's connected to the belts.
-Had all the service belts changed about 1 month ago.
-On way limping home, was going 60, then felt the car start slowing down as if I downshifted. Wouldn't go past 2500rpms or else it would choke. Coolant = GONE and temp. = WAY PAST H.
-Put some more coolant in, let engine cool, limped home, car ran fine (cept the PS issue).

Any ideas?
